Ball And Cup Model Of System Stability
Valleys represent stability domains balls represent the system and arrows represent disturbances.
Ball and cup model of system stability. In this framework the state of the system is represented by the position of a ball rolling on a surface. Low stability moderate resilience moderate stability low resilience a b fig. The cup represents its current domain of attraction. 2003 in this framework the state of the system is represented by the position of a ball rolling on a surface.
